Co- 1.0.8.2 Conductivity More Than 14.5 Ms/Isolate Drain Stream; O- 1.0.8.3 Drain Flow Pulse - Stop/[Conductivity] More Than 14.5 Ms - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 1.0.8.2 CONDUCTIVITY] MORE THAN 14.5 mS / ISOLATE DRAIN STREAM.
a) ENSURE Loading Pressure (Acid Rinse Port gauge) continues to reach its high of more than 22 psi!
IMPORTANT!
b) If a 'Quick Connector' (Figure
right) is present at the end of the drain tubing an
ADAPTOR is required!
c) As seen in the Figure (below right), point the drain
UP at 45°
tubing opening
than two (2) feet above the floor!
DOWN GRAVITY FLOW RESULTS IN
ERROR!
d) Watch for ONE (1) FULL MINUTE!
e) Consider BOTH scenarios below AND proceed
accordingly:
Scenario #1:
See Figure A. Approximately 30 ml pulses that stop between each and every
cycle i.e. Pulse → Stop → Pulse → Stop → etc. Reconnect the drain then see
procedure number
Figure A
Scenario #2:
See Figure B. If a continuous weak stream that LASTS for several seconds or
longer! ENSURING the drain tubing opening was pointed up, proceed to
procedure number
Figure B
CO- 1.0.8.3 DRAIN FLOW PULSE → STOP / [CONDUCTIVITY] MORE THAN 14.5 mS
A) Return BOTH concentrate connectors to their RINSE ports
B) Close the shunt door!
IMPORTANT! Place the machine into RINSE!
C)
D) Is the external flow indicator's 'bob' moving at least ¼ up in the sight tube?
holding it no higher
